Battery Laboratory
The transformation of transport and energy is gaining increasing momentum causing significant challenges for politics, industry, and society. The expansion of the application of renewable energie sources necessicate technological solutions to stabilize the energy supply grid. Moreover, the number of mobile electric appliances is steadily increasing, rendering having reliable battery storage systems crucial.
The battery laboratory of the chair of Electromobility and Energy Storage Systems, which will be put into operation in 2022, offers the opportunity for in-depth research into scientific issues arising from the related challenges mentioned earlier. For this purpose, the chair has various testers and temperature cycling cabinets at its disposal that enable battery research at both cell and module levels and allows for running different battery management systems (BMS) tests.
